Settlement Overview

 On June 26, 2009, DEP, Jersey City and PPG signed a settlement in Superior Court where they agreed to work together to clean up PPG’s chromium sites.  The agreement:

• Establishes a 5-year goal to clean up all 20 sites;
• Creates new position of an independent,

court-appointed Site Administrator;

• Creates new position of an independent Technical

Consultant; and among other things,

• Directs the Site Administrator to recommend

chromium health studies, if necessary

Settlement Health Exposure Study Requirement

 Review chromium-related health studies concerning health impacts in Hudson County  Consult with experts in the field  If necessary, recommend a health exposure study that would monitor the people living within the vicinity

• f the Garfield Avenue Site

Cr(VI)-Related Health Effects

 Respiratory, Nasal, Skin and Kidney effects  Increased risk of lung cancer  Depends on dose and exposure route

• How much and how long
• How exposed: ingested, inhaled, skin contact

 Most known effects based on epidemiological studies of

• ccupational exposures
• Workers exposed at much higher levels

Health Studies Reviewed

 Studies Specific to New Jersey

• Health Studies in 1990s
• Household Dust Studies, 2006-08 (EOHSI)
• Lung Cancer Incidence Study, 2008 (DHSS)

 Studies Outside New Jersey

• Community Studies (published 2001-09; data from

1970s-2000s)

• Occupational Studies (1980s -2009)

1990s Hudson County Studies Summary Results

 Early 1990s studies showed correlation between proximity to CCPW sites and level of total Cr in household dust  Children in households with elevated Cr in dust had higher Cr in urine  Follow-ups at homes near CCPW sites that were remediated showed significant decline in total Cr in household dust

Chromium in House Dust Pre v. Post-remediation

 In 1992-93 study, homes were identified as having had high (> 500 ppm), medium (100-500 ppm) or low (< 100 ppm) total Cr in house dust  23 homes re-sampled in 1996-98  Homes primarily from 3 neighborhoods: Metrofield, Siedler/Madison, Dwight St./Stegman St.  Previously high and medium-level homes saw approx. 85% decline in Cr concentrations

• High-level: median declined from 739 ppm to 50 ppm
• Medium-level: median declined from 245 ppm to 34 ppm

Jersey City CCPW Sites Status 2009

 145 Jersey City Sites identified in 1980s  Since then:

• 50 sites entirely cleaned up (NFA)
• Approximately 40% of all Jersey City Chromium

Sites have been investigated and cleaned up

• 46 PPG sites cleaned up
• 19 investigated and found not contaminated
• 76 awaiting cleanup, but capped or underground
• 18 PPG sites now under 5-year Master Schedule

 Public Comment/Q&A

Health Study

 Key questions for any community health study are:

1.

Will the data gathered to detect a specific contaminant (chromium waste) aid in the prevention of disease or health effect?

2.

How will the information be used to:

1.

Protect community health;

2.

Address community concerns; and

3.

Take appropriate action?

3.

Are there programs/resources in place to act on findings, if necessary?

4.

What follow-up will occur and who is responsible?

 Public Comment/Q&A

 Jersey City does not use groundwater for its drinking water supply  Clean, uncontaminated drinking water in Jersey City comes from Boonton Reservoir, located in Morris County, and Split Rock Reservoir in Rockaway  Contaminated groundwater will be treated as part of the cleanup plan, but will not be used as drinking water

Drinking Water

Other Health Topics, continued

 Air Monitoring During Remediation

• Cleanup will be conducted using proven dust-control

practices

• A combination of permanent and mobile

Air Monitoring Stations will continuously check to make sure that safe conditions are maintained during all cleanup activities

• Work will be halted if conditions require

 Residential Inspection and Sampling

• Workshop January 21, 2010
